MILK -BOTTLING MACHINE.

Specification of Letters Patent.

Patented Sept. *7, 1909.

Application filed January '23, 1908. Serial No. 412,259.

To all whom it may concern:

Be is known that we, GUSTAVE STRANDT and AUGUST H. NIEMANN," ofMilwaukee, Wisconsin, have invented a Milk-Bottling Machine, of whichthe following is a speci-- fication.

This invention is a machine particularly designed and adapted forbottling milk; although it maybe found adaptable to the bottling ofother liquids with such changes asv 'may be called for by the specialcircumstances and conditions present.

As is well understood, milk is put up for the retail market inwide-mouthed bottles, usually in quart, pint or half-pint sizes. We aimto provide an apparatus superior to any heretofore existing in rapidity,efliciency and cleanliness. The principal defect in existing machines,aside from slowness and inconvenience inhandling, consists in the factthat they spill the milk on the outside of the bottle. This results in alarge proportion of waste, and moreover, what is equally objectionable,the bottle is so coated on the outside with milk, as soon as the film isdry presenting a dirty and unwashed appearance which renders themunsalable. This defect is .also especially conspicuous in the case ofnicked bottles. Owing to careless and rough handling, the edges of the"mouths of the bottles become nicked so that they can no longer becompletely closed by the receiving apparatus which delivers the milkfrom the tank into the bottle. In our invention we provide means whichabsolutely prevents the milk from exuding and falling on the ex teriorof the bottle, not only in the case of whole and perfect bottles, buteven in the case of nicked bottles. We further provide av guiding-meansfor setting the bottles,-

means for shiftin filled bottles into a position suitable for insertingthe sto pers and placing them in the crates; means or adjusting themachine to different sizes of bottles: and other accessory andsubordinate devices, which will hereinafter appear and which areparticularly claimed at the end of this specification.

In the accompanying drawings, which illustrate an approved form of ourbottlefiller, Figure 1 is a front elevation of the machine, theright-hand half being shown partly in section; Fig. 2 is a side viewthereof with one of the frame-posts removed; Fig. 3

is a plan view; Fig. 4 is a partial horizontal section taken on theplane indicated by the line 4 of Fig. 1; Fig. 5 is a partial verticalsection on the plane indicated by the line 5 of Fig. 1, on a largerscale; Fig. 6 is a longitudinal section on a large scale of one of ourspecial automatic tank valves; Fig. 7

is a plan View thereof; and Fig. 8 is a longi- "tudinal section of thesame in a plane at right angles to that of Fig. 6 showing its action infilling a milk-bottle.

In these drawings every reference letter and numeral refers always tothe samepart.

The apparatus comprises, broadly speaking, a frame supporting anelevated tank, "and a bottle-filling mechanism mounted on the frameunder said tank. The supporting-frame, while it may be constructed invarious ways, is very conveniently, cheaply and strongly made by meansof gas-pipes, consisting of four corner posts 11 which are each dividedintermediately by a four-way tee 12, three horizontal lengths ofpipe 13uniting the four posts at the sides and back by means of the tees, and atransverse bar 14 across the front, which serves in part to support thebottle-filling mechanism as will be hereinafter described, and hasscrewbosses 15 upon its ends engaging in the openings of the tees. Theupper ends of the posts 11 are closed by means of plugs 16 threadedholes in the beam as shown, and

holes 22 are formed to register therewith in the bottom of the tank 20,which is hermetically secured to the beam 17.1:0 prevent leakage. Thespecial construction of the valves 20 will be hereinafter described; atpresent it is suflicient to say that they are arranged to closehermetically the mouths of the bottles when pressed thereagainst and bythe same pressure to open and deliver milk thereinto, closing whefi thepressure is removed.

The two front-posts 11, besides being joined by the transverse bar 14,are also connected lower down by a second transverse bar 23, which haslugs 24 fitting the posts and is secured'to the latter by cap-screws 25.

' to be out of ,the' way when not in use.

' mounted a rock-shaft 35, and on this shaft 35 are mounted rock-arms36, which are connected by means of links 37 to pivot-' blocks 38secured upon the vertical rods 28 'in any approved manner, as bytransverse pins 39. One of these pivot-blocks 38, (that on theright-hand side in Fig. 1) has its pivot-pin 40 extended and providedwith a collar.41, so as to form a seat for a notched bar 42 pivoted at43 to the under-side of the leaf 33, and having a notch 44 (see dottedlines in Fig. 2) for that purpose. This enables 'the leaf 33 to behorizontally extended or to be dropped into vertical position so as Onone end of the shaft 35 is mounted a hand-lever 45, which. carries aspring-bolt 4'6, and adjacent to the lever on the post 11 is fixed aplate 47 having a series of holes 48 therein, in which the bolt 46engages. These holes will be in ordinary practice three in number,corresponding to the three sizes of bottles used in the trade, to wit,quarts, pints, and half-pints. It will be seen that by oscillating thelever 45 the vertical bars 28 and consequently the platform 29 is movedup and down and adjusted in position so as to be closer to or fartherfrom the valves 21. v In the platform 29 are a number of circularrabbeted orifices, in each of which is set a circular-platen 49. Eachplaten 49 is mounted on the end of a vertical rod 50 which passesthrough and has hearings in perforated lugs 51, 52 on the transversebars 14 and 23 respectively. Each platen 49 with its bar 50'is in axialline with one of the valves 21, the whole number corresponding tothenumber of bottles which the machine is adapted to fill atone time. Thepresent machine possesses four valves and four platens 49, as we havefound it most convenient for ordinary hand-work'to fill four bottles atonce. Each of the bars 50 passes through a hole in a transverse bar 53,and is resiliently connected therewith so as to beraised thereby bymeans of a coiled compression spring 54 resting on the bar and abuttingat its upper end ,on a collar 55 secured upon the rod 50. The bar 53 maybe called a lifting bar, because it acts to raise simultaneously theplatens 49 and the botverse shaft 57 which turns in handle 68 extendingmoving the. bottles away after they tles which rest upon then'r -anditisoperatedpedal 56 mounted on a transbearing-blocks 58 on the rear side ofthe posts 11. The shaft 57 carries a forked arm 59 on which is by meansof a pivoted a sheave 60, and a pair of similar sheaves 61 are mountedto turn on stationary pins 62 on the bar 14. A chain 63 is secured atone end to a pin 64 on the rib 30 of theplatform 29, and passes downaround the sheave 60, loeing then divided into two chains, as shown,which pass respectively around the sheaves 61, and have their endssecured to the lifting-bar 53. From this construction it will be evidentthat the depression of the pedal 56 draws upon the chain 63 and causesthe lifting-bar 53 .to be raised; The raising and lowering of theplatform by the adjusting-lever 45 does not affect the position ofthepedal 56 in any way, as thehar 53 is moved up and down along with theplatform, so that the pedal 56 is always in the same posit-ion and thedepression thereof acts merely to raise the platens a short distanceabove the platform wherever that may be.

In order to provide for a rapid and accurate centering of the bottleswith respect to the valves 21, there is arranged imme-' diately over theplatform 29 a centering-bar. 65, which is pivoted at-"one end uponashouldered pin 66 mounted in the platform, and at the other end abutsupon a in 67 therein,

table 33'. This centerin -bar is raised somewhat above the level 0 theplatform so as this end being prolonged to orm a over the edge of the topermit the raising and lowering of the platen 49 without interferingtherewith.

To this end the pivot-pin 66 is shouldered -as shown in Fig. 1, and theopposite end of the platform and the curved margin of the table 33 areprovided with an upstanding rim 69 on which the projecting handle 68rests. The centering bar has a number of recesses 70, corresponding tothe number of platens, and these recesses are-of such shape that whenthe bar is set in either of .its three positions, sponding size ifpushed up against the hack of the recess will be brought to a stop whenexactly in the center of the platen below it.

For this purpose the pivoted end of the centering-bar is provided withthree holes 71. adapted to receive the pin 66, and the other end isprovided with three corresponding notchesor shoulders 72 in a lineparallel to the line joinifigthe holes. 71. Besides serving as acentering bar in the manner described, the'bar 65 also serves forquickly are filled, being for this purpose turned about its pivot 66inthe manner illustrated in Fig. 3, and a stop-pin movement,

brought into by which the bottles 74 are the position shown in Fig. 3,

a bottle of the corre- 7a being-provided to limit the-Z outside of thebottle.

and left there while the bar 65 is moved .back again into position forreceiving another set of bottles.

Our special form of valve,.illustrated in Figs. 6, 7 and 8, forms one ofthe most im- .portant elements of our-invention and we have found it tobe essential to the successful operation of our device enabling thebottle to be filled quickly and automatically with out spilling asingle,drop of milk upon the The valve-body or casing is made in twoparts which fit one within the other, designated 75 and 76 respectively. The member 75, which is the "outer member, has a threadedboss 77 engaging the threaded hole in the bottom of having a shoulder orcollar 84 abutting upon the upper side of the lug 79 and drawing the twomembers 75, 76 together. The airtube 83 extends up to above the surfaceof the liquid in the tank, and may be provided at its upper endwith'wings 85v whereby it inay be screwed up and unscrewed whennecessary.

The openings of the passage-ways 80 and 81 in the member 76 areseparated by a head 86 whose upper conical surface 87 is faced to form aseat, on which rests the correspondingly ground end of a tubular sleeve88'which fits, closely over the tubular portion of the outer member 7 5.This sleeve 88 has a shoulder 89 forming an abutment for a coiledcompression spring 90 surrounding the sleeve and abutting at its upperend within an annular recess 91 formed in the body-member 75. The'sleeve 88 also carries around its lower margin a sealing memberconsisting of a gasket or washer 92 of elastic nonporous material suchas soft rubber, and this gasket abuts upon the shoulder 89 and may havean annular tenon 93 received by a groove therein to hold it in place.Inparticular the gasket 92 has a long tapering downwardly extending lip94, and this serves a most important function in the fulfilment of theperfect operation of the device. Were it merely a question 'of sealingthe mouths of bottles whose mouths are perfectly round and even, therewould be no difficulty and an ordinary rubber gasket would sufiice; butthis no longer serves its function when the edge of the bottle-mouth ischipped or broken, as is the case with a great'many. of the bottles inactual use. We .have therefore" only by much and extended experimentinginvented and devised the form of sealing-gasket here shown, and itsexact mode of action is made clear from Fig. 8, in

sumes when a bottle-mouth is pressed up against it. It Will be notedthat the bottlemouth is of such diameter as to press upon the outermargin of the gasket 92, and this together with the shoulder 89 forms acouple which distorts the gasket and causes the lip 94 topress outwardlyagainst the inner surface of the neck of the bottle. Now as soon as thebottle is full, the pressure of the liquid which is shown the positionwhich it as- 70 from within acts further'to distend the lip 94 and pressit against the inner. surface of the bottle and thus seal the mouth ofthe bottle independently of any nicks or irregularities in the edgethereof- The mode of operation of the device is as 8 follows: Theoperator stands at the left of the machine with one foot on the pedaland faces toward the right-hand corner, the bottles to be filled beingat the-left or in front of the machine, and the crate or shippingcasefor the filled bottles in front of the open-spaced side of the table 33on the right.

A set of bottles being now placed upon the platen and pushed up againstthe centeringbar 65, the operator presses upon the pedal 95 for a fewmoments which raises them until their mouths press upon gasket 92 andslides the valve-sleeve 88 up, thus permitting milk to enter the bottlethrough the passage 80,

while at the same time the air escapes through the passage 81 and pipe83. The under side of the valve-head 86 may be hollowed out as shown at95 to prevent any air from becoming trapped below the valvehead and toprevent milkfrom being drawn into the air-vent and sealing it. As soonas 83 to the level of the liquid in the tank, this i the bottle is full,the liquid rises in the pipe operation lasting but a fraction of aminute, and when completed the operator releases the pedal, and thebottles descending allow the sleeves to be closed by the springs 90,

and thereafter are unsealed. from the gas kets 92 The small quantity ofmilk in the passage 81 and tube 83 is just sufiicient, or

a little lessthan 'suflicient, to fill up the empty space in thebottlepreviously filled by the end of the valve. The valve-seat and valvebeing ground accurately, it is thus impossible for a single drop of milkto escape. The operator now swings around theobar 65 and back againmoving the filled bottles-to the right-hand side of the table, places afresh set on the platen, and while these are filling his hands are freeto insert stoppers in the mouths of the filledmilkbottles and place themin the crate or shipping-case.
